My 422 smallblock build

I found a professional weld shop fairly local to me that supposedly has the ability and experience to make the necessary repairs. I will be dropping the wounded head off at their place in the next week or so. They said that they would like to bead blast it clean and mag the entire thing for cracks. I’m going to give it a shot.

On another front, I’ve been searching for a good deal on a carburetor for this engine. I currently have an ancient Holley 650 DP on the shelf but I don’t think that will be enough carb for the stroker. I found a low use 950 DP from Willy’s carb shop. I’m very tempted because the price is right but nervous that it might actually be too much carb. Any thoughts about the 950 on a 422 with W2s?
Appreciate your input.
